A groundbreaking study has traced the 66-million-year history of primates to overturn conventional thought that our ancestors came from tropical forests. The earliest members of our family tree, scientists say, were actually cold-climate survivors.

Researchers in Germany found fossilized dinosaur teeth can reveal what the air was like in prehistoric times. Humans might have found it hard to breathe if we were around back then, because CO2 levels were four times as high as the preindustrial era.

For centuries, glaciers have sat like frosty crowns atop slumbering volcanoes, keeping Earth’s fury tucked safely beneath layers of ice. But now, as climate change accelerates and glaciers retreat, the lid may be lifting, and the heat rising.

AI tools like ChatGPT have changed our personal and professional worlds, with around 52% of American adults regularly using a large language model. But at what cost? A new study details the large environmental price we're paying for our AI assistants.

In 2025, around 24 million Americans are estimated to suffer from sleep apnea, and around 90% of these cases are undiagnosed. Now, a groundbreaking new study warns that the prevalence of this serious condition will soar as the planet warms.

No Soviet records, no logs or official drilling reports – just a 100-foot (30-m) deep, 226-foot (69-m) wide pit of relentless fire that’s burned for 50-plus years in Turkmenistan’s Karakum Desert called the Door to Hell.

The construction work currently underway in Saudi Arabia is unprecedented, with buildings like the Line transforming the desert landscape. Now an expert has suggested that the scale of work is so massive, it could even alter weather patterns.

An alarming new report reveals that right across the country, 28 US cities are sinking, showing the kind of geologic subsidence that could impact buildings and infrastructure sooner rather than later. But, scientists say it's not yet too late to fix.

In what may not come as much of a shock, the Doomsday Clock has inched closer to midnight and is now just 89 seconds from 12. It's the closest the hands have ever been to the symbolic 'end of times' number on the clock face in its 80 years.

When the Swiss and Italian governments got together to redraw the alpine border that divides the two countries last year, due to rapidly retreating glaciers, it put into stark focus a challenge that is expected to face many nations that have natural structures that mark territories.

Researchers have linked hotter temperatures to a rise in suicidal thoughts and behavior in young people. The new study adds to existing evidence that rising temperatures are affecting the mental health of adult men and women, too.
